I use angstrum minerals and Sea Salt
when it is appropriate. No I do not use colloidal anymore, but in the past I used Colloidal minerals in clear distilled water. They were sold to me by a doctor in NYC and they did not bother me. However, I was very deficient back then.
I juice herbs, vegetables, fruits...throughout the day. That is my main source. If I need to, I take angstrum minerals at certain times of day. It takes time to find a good balance. People are naturally prone to certain deficiencies and it also depends on the type of stress you have in your life.
Obviously people with problems with Sugar
metabolism may need more chromium and vanadium. While those with thyroid problems might need copper.
Many people soak gems, crystals, rocks in water over time and drink the water. There are microbes in the soil and in our body that help to metabolize minerals.
Nature is the best source.
Thank you for your comments.
Have a great day,
